Questions.
Who is the Trial Pack for?
Anyone who hasn't used OPN yet, or knows one product and wants to try the rest before buying a full box. Runners, cyclists, HYROX athletes and anyone training long in the heat.
Electrolytes or gels — what's the difference?
Electrolytes replace the salt and fluid you sweat out. Gels give you carbohydrate for energy. Sessions over 60–75 minutes usually need both — that's why the pack has both.
How much water per electrolyte sachet?
500 ml for most sessions. Go up to 750 ml if you prefer it lighter.
Should I take ONE Gel+ on race day?
Only if you've already tried caffeine in training. That's what the Trial Pack is for. Not recommended for children, pregnant or lactating women.
Can I choose the gel flavour?
Both gels in the pack are Lemon Lime.
